China's air defense identification zone (ADIZ)

Abstract

In November 2013, the People's Republic of China (PRC, or China) announced that it would establish an "East China Sea Air Defense Identification Zone (ADIZ)," covering a large swath of airspace over the East China Sea, including over small islands that are the subject of a territorial dispute among Japan, the PRC, and Taiwan. Beijing did not formally consult with other countries prior to the announcement, and its initial statement seemed to warn that China might use force against aircraft that did not follow its ADIZ guidelines. Senior officials from the United States and East Asian countries criticized China's action and raised concerns that the new ADIZ could escalate tensions surrounding the territorial dispute and even lead to conflict.
